A study by researchers at Oxford University has found that playing video games can be good for children. The study found that children and teenagers who play the games for less than an hour a day show good behaviors in school and life. 

The researchers asked almost 5,000 people between the age of 10 and 15 in Britain how much time they spent playing video games. They also asked them how happy they were and whether they have good relations with their friends and other students. The researchers found that young people who spend less than one-third of their time away from school playing video games had the highest level of happiness. The researchers compared them to two other groups: those who didn't play games at all and those who spent three hours or more a day playing them. The study says that the influence on a child's life of video games -- whether good or bad -- was not nearly as great as the influence of family members, friendships.

Another study says that teenagers who play violent video games that give rewards for taking risk are more likely to take high risks in their lives. The study lasted four years. The researchers say people will spend more than $100 billion on video game activities worldwide by 2017.
